Do you 1) go hard and fast, with a burst of power from the get-go, or 2) take it slow and steady, to get the measure of her strength? Or you may know of another tactic.
Start slowly and gauge her strength
Ada lets go, and you tense your muscles...
... and Emily grunts loudly as she flexes, hard, and jerks your arm down halfway!
Immediately you're on the defensive, shaking and straining, feeling a sharp pain in your biceps. She got the jump on you! She bares her teeth as she strains to put your arm down. The line separating her deltoids and her upper arm muscles is sharper than before. Before your very eyes, her pink nipples become engorged, hardening with arousal. She may be about to win, and she knows it.
You groan. You've managed to stave off her first big attack, but now it's a contest of stamina, and you're at such a big disadvantage... can you turn this around? Do you have what it takes to outlast Emily's arm, bring her over the top? Or will you succumb to exhaustion before her?
